Title: Image forming device
Inventor: NAGATA JIRO
IPC: G03G15/00
Filed: 1987-01-29
Abstract: PURPOSE:To prevent an image carrier from generating uneven rotation by arranging elastic members for applying elastic force between members on the driving side and the driven side on non-circular torque transmitting parts. CONSTITUTION:Since torque obtained from a driving source is transmitted to the image carrier 32 through the optional stages of torque transmitting parts 2a, 2b constituting a power transmitting mechanism part 2, the image carrier 32 is rotated and supplied to an image forming process. At that time, the elastic members 12a, 10b arranged on the torque transmitting parts 2a, 2b having non-circular sectional areas in respective stages absorb inertia force generated on the driven side following to the uncontinuous rotation of the driving side by their elastic force. Consequently, the image carrier can obtain uniform torque.

Title: Mold for injection molding and injection molding method
Inventor: OTSUKI TOSHITAKA
IPC: B29C45/26
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To obtain an injection molding exhibiting low double refraction properties of norbornene resin by incorporating a mechanism inclined in an outer circumferential direction of the molding at a specific angle or more than a line for connecting a center of a gate to a center of the molding in a resin injection direction from a gate. SOLUTION: Since flow of molten resin becomes an outer circumferential direction of a molding, a strain (double refraction) generated in a gate part 3 is dispersed in an outer peripheral part of the molding, and not invaded into an effective surface of a center of the molding. The gate 3 has a mechanism inclined in an outer circumferential direction of the molding at an angle (which is θ) of about 10 degrees or more from a line for connecting the gate 3 to a center of the molding in a resin injection direction from the gate 3 between a runner 2 and a cavity 1. This angle θ is 5 degrees or more, and preferably 10 to 90 degrees or more preferably 15 to 60 degrees.

Title: Electric contactor
Inventor: HIMI HITOSHI
IPC: H01H1/38
Filed: 1991-02-08
Abstract: PURPOSE:To realize an easy manufacturing and a cheap price and moreover improve cooling effect and current carrying capability by punching and press- forming a segment for an electric contactor using a garter spring from a round bar, a round wire, or a plate material. CONSTITUTION:A round bar or a round wire of a predetermined length is bent in a U-shape centering around a1, and contact points b1 and b2 are stricken out in a circular shape at the bath ends of a parallel portion by a press-forming. Next, an angle theta is given by a press-forming such that respective contacts b1 and respective contacts b2 adhere to each other respectively. In the case where an electric contact is comprised of, for example, ten pieces, since theta=360 deg./10=36 deg., the angle theta is designed to be narrower than 36 deg. by the angle of a gap. In the electric contact using the segment, the gap is zero in the open state so that a contactor part is maintained circularly uniform. Besides the surface area is large so that cooling effect is efficient, and further the number of the contact points with a movable contactor is two, thereby large current- carrying capability can be obtained.

Abstract: PURPOSE:To obtain a fuel tank which makes no trouble in filling fuel therein by providing an exhaust valve, which opens and closes according to the quantity of fuel in the first auxiliary chamber, at the end of a fuel transfer pipe. CONSTITUTION:Even if the fuel is shifted to the first auxiliary chamber 17 side, the tip part 51a of a fuel take-out pipe 51 is located below the fuel surface W so that it can take out the fuel without any trouble. If the fuel surface W is located on the opposite side of the first auxiliary chamber 17, sufficient amount of fuel is secured in the first sub-chamber 17. If the fuel level lowers down to WL, until a discharge valve 31 is exposed to the air because of a long turning time or because of fuel consumption during idling in an inclined posture of a car, then the valve 31 opens, and the fuel in the second auxiliary chamber 19 is sent into the first auxiliary chamber 17. Thus, quantity of fuel is regulated to secure the fuel supply.
